Title: Improvements in or relating to a system comprising a plurality of rotor-fed three-phase current shunt commutator motors
IPC: H02K27/18
Filed: 1945-03-21
Abstract: 596,665. Control of several A.C. motors. MASCHINENFABRIK OERLIKON. March 21, 1945, No. 7178. Convention date, April 4, 1944. Drawings to Specification. [Class 38(iii)] A plurality of rotor-fed three-phase shunt commutator motors of types similar to the Schrage motor are run down in synchronism by maintaining the connection of the motor primary windings to the supply, moving the brushes to a subsynchronous position, disconnecting the leading brushes from the trailing brushes, and interconnecting the stator windings of corresponding phase positions, which are connected to the trailing brushes, by equaliser connections which may comprise impedances which may be short-circuited during running-down. The switches for disconnecting the leading and trailing brushes may be of the type in which a sliding contact connects with a "make" contact before disconnecting from a " break " contact, in which case the corresponding leading brushes are interconnected through impedances for a short period during switching-over. Each phase of the stator windings may comprise two sectional windings which are connected in parallel during running-down, the ends of the windings which are disconnected from the leading brushes being connected to a corresponding sectional winding of another motor. The corresponding stator windings of each motor may be permanently interconnected through a common equaliser connection, and the leading brushes may be interconnected through another compensating lead comprising impedances, the two equaliser connections being convertable through a switch. Interlocked drum switches may be provided, one for each motor, each having a starting position intermediate a running down and an operating position, the starting resistances being effective for a short period when changing over from running to running down. The running-down connection may be automatically effected on the return of the brushes to a pre-determined low-speed position.

Class 26 A water-waste-preventing cistern of the "normally empty" type and comprising a tube 6 which is rockable to close the discharge orifice 2 and open the inlet valve- 20 by a .rod or link system and which is. rocked back by a float 40 to open the discharge orifice when the cistern has been filled is characterized in that the tube 6 is rocked by means of a lever, pivoted to the inlet valve body, and having two parallel arms 13 provided with guiding slots 12 fora guide member 10 attached to the tube 6 and which arms also serve as a support for a roller or equivalent member 19 adapted to control the opening of the inlet valve 20. In the empty position, Fig. 1, inlet valve is closed by the supply pressure, and the tube 6 rocked back to open the discharge orifice 2. When the chain on the lever 16 is pulled, the tube 6 is rocked forward by the arms 13 and guide member 10 and held inthe "orifice-closed" position by a latch on the float lever 36, and the inlet valve 20 is opened by the roller 19 on the arms 13. The water in the tank rises and lifts the float 40 thus releasing the tube 6 from the latch so that the tube rocks and the discharge orifice opens due to the weight of the arms 13. The inlet valve 20 is simultaneously closed.

Title: Improvements in or relating to treating silica-magnesia catalysts
IPC: B01J21/14
Filed: 1955-03-22
Abstract: The surface area and pore volume of silica-magnesia catalysts are increased by subjecting a hydrogel or aqueous slurry of the catalyst to a pressure of 200-800 p.s.i.g., and a temperature of 350 DEG -600 DEG F. in an enclosed zone and then releasing water vapour from the zone while supplying additional heat to maintain the pressure until the catalyst is substantially dry.  The catalyst may be heated in an autoclave for 0.25-4 hours and then the water vapour released for a period of 1-6 hours.  Up to 20 per cent of water may remain in the catalyst and this is removed by heating at 1000 DEG -1300 DEG F. for 2-6 hours.  The treatment may be applied to freshly prepared hydrogel, to standard activated catalyst, or to used catalyst.  A major proportion of the surface area, pore volume, and activity of the catalyst is maintained after steaming. The catalysts are suitable for the cracking of hydrocarbons.  The catalyst may contain 20-35 per cent magnesia and may be prepared by mixing silica sol (formed from sodium silicate solution and sulphuric acid), with a slurry of finely ground magnesia and washing the resulting hard hydrogel.

Abstract: 731,205. Pit props. KRAUT, H., and DOELL, W. March 26, 1953 [March 27, 1952], No. 8333/53. Class 20 (2). A stanchion, pit prop or like load carrying element consists of a pair of telescopic members in which the force acting to close the members one into the other is applied as an upthrust to a settled mass of granular material which fills only partially a hollow space within one of the members. A pit prop consists of an upper prop member a having an annular space d which slidably receives an abutment f formed on the upper edge of the lower prop member e. The granular material g, such as sand or steel shot, is supported on the abutment f and partly fills the space d. The prop is initially set by a wedge h being passed through slots in the lower member e, this assembly operation causing the granular material to be shaken down into a settled state. Thereafter the wedge h is removed, and load on the prop is taken by the granular material. In order to collapse the prop, air is injected through the pipe i into the space d, which disperses or unsettles the granular material to break down its holding effect.
